Nice ! I'm surprised to see this kind of nicely done "selling" brochure back then in the USSR. Only the state could make the decision to buy these things, even civilian.
So it was for the decision makers maybe ? Like ministers... Army officials ?
I guess being an aerobatic aircraft there would have been more reason to promote the Yak-32. The 1961 data of the brochure coincides with their debut display at Tushino that year.
There might also have been an expectation that it might have replaced the piston Yaks as the official aerobatic mount of choice and perhaps for other Eastern Bloc display teams too.
